Problem: The client was experiencing an issue where product categories were showing duplicate products in different languages, alternating between German (DE) and English (EN), despite not being new products and having worked correctly for many years.
Solution: We identified that the issue might be due to a conflict with cache settings, specifically involving the Redis cache and the Breeze plugin with Varnish cache configured. We recommended the following steps: 1. Disable the Redis cache or configure it properly. 2. Disable the Varnish cache or configure it properly. As a workaround, we suggested changing the Product Category slug for the German version from
ktm-250-exc
to
ktm-250-exc-de
and then clearing the caches to see if the issue persists.

Problem: The client's multilingual WooCommerce website experienced a disappearance of products in the translated languages (FR, DE, and USA). The issue was resolved by using the "Synchronize posts taxonomies" button, but the client sought an explanation for the cause and how to prevent it in the future. Solution: We explained that it is challenging to pinpoint the exact cause without further investigation. However, such issues may arise if: 1. Content was created while WPML or its add-ons, such as WooCommerce Multilingual (WCML), were disabled. 2. There is a conflict between WPML and another plugin, possibly a WooCommerce Addon. We recommended that if the issue reoccurs, the client should allow us to take a copy of their site for debugging and to attempt to recreate the issue. This would enable us to run troubleshooting steps to determine the cause. Please note that this solution might be irrelevant due to being outdated or not applicable to your case. If the issue persists, we highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
